Mum-to-be Kelly Rowland accidentally revealed the gender of her baby during an interview on Thursday (31Jul14).

The former Destiny's Child singer and her husband Tim Witherspoon are preparing for the birth of their first child, and during an interview with Fox News Channel, she let it slip that they will soon be parents to a baby boy.

Talking about her pregnancy journey, Rowland said, "We’re very excited. So far, everything has been good. I just feel like the baby is already (spoiled) rotten - like, literally, my (beauty brand) Caress family has gotten him all of his little bathing stuff, his toys - it's just so cool."

Rowland quickly realised she had 'outed' her baby as a boy, and exclaimed, "It, it's... oh, f**k it! It's a boy. It’s a boy!"

She then told her representative, "Can you please tell him (Witherspoon) that I spilled the beans? I'm sorry, baby. But yes, it's very exciting."
